    I learned it in Hassan Zadeh A. and Amirhashchi S., “Modelling Joint Lifetimes of Couples by Using Bivariate Phase-type Distributions”, that paper should be easily to find in Arvix. The referenced paper, “Young, the mortality of widowers 1963, Lancet”, it’s pretty hard to find but I got my university to pay for a copy for me, if you DM me your email I can send you a copy.
